A very well done film, constantly having you ask "what is next?" Leaving you in the dark but with enough information that you feel like you understand where it's going.
I thought it was great, my wife and I are huge film nerds and specifically love horror. Some of our favorites are the Conjuring and Insidious series, IT, Sinister etc. Spirit Of Fear is close to those films but their budget was definitely a factor that kept it from breaking into the 9/10 and 10/10 area.
Some people seem to not be satisfied but I don't understand them to be honest. Go in with no expectations and just enjoy it. Sure, it isn't the greatest film or horror film we've ever seen but in no way did it disappoint.
Enough of my rambling... 8/10.
